* ralloc: Implement a new ralloc_adopt() API.Kenneth Graunke2015-04-022-0/+33
| | | | | | | | | | | | | | | | | | | | | ralloc_adopt() reparents all children from one context to another. Conceptually, ralloc_adopt(new_ctx, old_ctx) behaves like this pseudocode: foreach child of old_ctx: ralloc_steal(new_ctx, child) However, ralloc provides no way to iterate over a memory context's children, and ralloc_adopt does this task more efficiently anyway. One potential use of this is to implement a memory-sweeper pass: first, steal all of a context's memory to a temporary context. Then, walk over anything that should be kept, and ralloc_steal it back to the original context. Finally, free the temporary context. This works when the context is something that can't be freed (i.e. an important structure). Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

* util: Optimize _mesa_roundeven with SSE 4.1.Matt Turner2015-03-181-0/+20
| | | | | | | | | | | | The SSE 4.1 ROUND instructions let us implement roundeven directly. Otherwise we assume that the rounding mode has not been modified (as we do in the rest of Mesa) and use rint(). glibc uses the ROUND instruction in rint() after a cpuid check. This patch just lets us inline it directly when we're already building for SSE 4.1. Reviewed-by: Carl Worth <[email protected]>

* mesa: Replace _mesa_round_to_even() with _mesa_roundeven().Matt Turner2015-03-182-0/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eric's initial patch adding constant expression evaluation for ir_unop_round_even used nearbyint. The open-coded _mesa_round_to_even implementation came about without much explanation after a reviewer asked whether nearbyint depended on the application not modifying the rounding mode. Of course (as Eric commented) we rely on the application not changing the rounding mode from its default (round-to-nearest) in many other places, including the IROUND function used by _mesa_round_to_even! Worse, IROUND() is implemented using the trunc(x + 0.5) trick which fails for x = nextafterf(0.5, 0.0). Still worse, _mesa_round_to_even unexpectedly returns an int. I suspect that could cause problems when rounding large integral values not representable as an int in ir_constant_expression.cpp's ir_unop_round_even evaluation. Its use of _mesa_round_to_even is clearly broken for doubles (as noted during review). The constant expression evaluation code for the packing built-in functions also mistakenly assumed that _mesa_round_to_even returned a float, as can be seen by the cast through a signed integer type to an unsigned (since negative float -> unsigned conversions are undefined). rint() and nearbyint() implement the round-half-to-even behavior we want when the rounding mode is set to the default round-to-nearest. The only difference between them is that nearbyint() raises the inexact exception. This patch implements _mesa_roundeven{f,}, a function similar to the roundeven function added by a yet unimplemented technical specification (ISO/IEC TS 18661-1:2014), with a small difference in behavior -- we don't bother raising the inexact exception, which I don't think we care about anyway. At least recent Intel CPUs can quickly change a subset of the bits in the x87 floating-point control register, but the exception mask bits are not included. rint() does not need to change these bits, but nearbyint() does (twice: save old, set new, and restore old) in order to raise the inexact exception, which would incur some penalty.

Unfortunately we still need MSVC 2008 on a few portions of the code (namely llvmpipe and its dependencies). I hope to eventually eliminate this so that we can use C99 everywhere, but there are technical/logistic challenges (specifically, newer Windows SDKs no longer bundle MSVC, instead require a full installation of Visual Studio, and that has hindered adoption of newer MSVC versions on our build processes.)

* ra: Disable round-robin strategy for optimistically colorable nodes.Francisco Jerez2015-02-231-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The round-robin allocation strategy is expected to decrease the amount of false dependencies created by the register allocator and give the post-RA scheduling pass more freedom to move instructions around. On the other hand it has the disadvantage of increasing fragmentation and decreasing the number of equally-colored nearby nodes, what increases the likelihood of failure in presence of optimistically colorable nodes. This patch disables the round-robin strategy for optimistically colorable nodes. These typically arise in situations of high register pressure or for registers with large live intervals, in both cases the task of the instruction scheduler shouldn't be constrained excessively by the dense packing of those nodes, and a spill (or on Intel hardware a fall-back to SIMD8 mode) is invariably worse than a slightly less optimal scheduling. Shader-db results on the i965 driver: total instructions in shared programs: 5488539 -> 5488489 (-0.00%) instructions in affected programs: 1121 -> 1071 (-4.46%) helped: 1 HURT: 0 GAINED: 49 LOST: 5 v2: Re-enable round-robin already for the lowest one of the nodes pushed optimistically onto the sack (Connor). v3: Use UINT_MAX instead of ~0, open-code MIN2 (Jason, Connor).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't actually have the code for the shader cache just yet, but this configure machinery puts everything in place so that the shader cache can be optionally compiled in. Specifically, if the user passes no option (neither --disable-shader-cache, nor --enable-shader-cache), then this feature will be automatically detected based on the presence of a usable SHA-1 library. If no suitable library can be found, then the shader cache will be automatically disabled, (and reported in the final output from configure). The user can force the shader-cache feature to not be compiled, (even if a SHA-1 library is detected), by passing --disable-shader-cache. This will prevent the compiled Mesa libraries from depending on any library for SHA-1 implementation. Finally, the user can also force the shader cache on with --enable-shader-cache. This will cause configure to trigger a fatal error if no sutiable SHA-1 implementation can be found for the shader-cache feature.

| | | | | | | | | | | | | | | | | | | | | | | | Previously, the set API required the user to do all of the hashing of keys as it passed them in. Since the hashing function is intrinsically tied to the comparison function, it makes sense for the hash set to know about it. Also, it makes for a somewhat clumsy API as the user is constantly calling hashing functions many of which have long names. This is especially bad when the standard call looks something like _mesa_set_add(ht, _mesa_pointer_hash(key), key); In the above case, there is no reason why the hash set shouldn't do the hashing for you. We leave the option for you to do your own hashing if it's more efficient, but it's no longer needed. Also, if you do do your own hashing, the hash set will assert that your hash matches what it expects out of the hashing function. This should make it harder to mess up your hashing.
